Woah! a park playground we went to occasionally as a elementary school kids had this (exact model?) robot with the slide; I remember you could go up in his head too. As a kid I remember this thing being HUGE, though.

Haha! I was there for that. We got to Roppongi and wandered around a bit, and when I saw the robot standing there, my first comment to my friends was "I wonder when that thing starts to spit fire and stomp on all the kids here?" Less than five minutes later it was spitting fire. Alas, there was no child stomping to be had. I should've demanded my money back.

(Feeling too lazy and jetlagged to get my pics from that night uploaded/linked)
